Ouch! That's inexcusable behaviour towards her kids and kind of ridiculous to be honest. The amount of time it takes to change a diaper is all of 2 minutes and what the heck is she doing throughout the day to neglect the child to the point that they are not being changed? Not sure its just because she is taking an hour out of her day to exercise. That simply wouldn't result in diaper wash...must be more to it I think.
Fad diets brainwash the best of us at some point with the "promise" of fast weight loss. Add to that a so called "professional" telling them its okay to do it, I can understand how she could have her head in the clouds. She will learn soon enough. If you are on any kind of "diet" you are doomed to fail eventually. Its not sustainable to eat a highly restricted meal plan. Balance in all areas of life is where success lies but we are surrounded by so many influences brainwashing us to think and believe otherwise. Not to mention the fact that it is easier said than done.
